Entangled Top Quarks at the LHC measured with the CMS Detector at √s = 13 TeV

Measurements of the entanglement of top quark pairs utilizing spin correlations are presented using events containing two leptons produced in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the CERN LHC in 2016 and correspond to an integrated luminosity of 35.9 fb^-1. The extent to which top quarks are entangled is measured by an entanglement proxy, which is optimized to have maximal sensitivity.
